Compare
Ancla vs Fly.io
Fly.io is a powerful platform with a genuinely impressive global edge network. It also has a learning curve that rivals some cloud providers. Here is how the two platforms compare when simplicity matters as much as capability.
At a glance
The trade-off
Ancla
- ◆ Predictable pricing
$19/mo flat for 1 vCPU + 2 GB. No usage math.
- ◆ One-command deploys
ancla deploy— no config files to learn. - ◆ Truly managed Postgres
Backups, failover, upgrades handled for you.
- ◆ Zero egress fees
No per-GB charges. Ever.
- ◆ Sub-second rollbacks
Instant revert to any previous release.
Fly.io
- ◆ Global edge network
Anycast routing, 30+ regions. Genuinely excellent for latency-sensitive apps.
- ◆ WireGuard mesh networking
6PN private networking between apps. One of their strongest features.
- ◆ Usage-based billing
Pay for what you use. Requires careful monitoring to avoid surprises.
- ◆ Steep learning curve
Fly.toml, Machine API, flyctl concepts take real time to learn.
- ◆ Postgres complexity
Free Postgres is self-managed. Managed Postgres (MPG) starts at $38/mo.

Context
Power comes with trade-offs
The complexity tax
Fly.io is built for developers who want low-level control over global infrastructure. Their Anycast edge network and WireGuard mesh are genuinely impressive engineering. But that power comes with a learning curve: Fly.toml configuration, the Machine API, volume management, and a CLI that exposes concepts most PaaS platforms abstract away. For teams that need global edge compute, that trade-off makes sense. For teams that need to ship a web app and move on, it can feel like solving the wrong problem.
The Postgres question
Fly.io offers two Postgres options. Their original Fly Postgres runs inside Fly VMs and is self-managed — you handle backups, failover, and upgrades. Their newer Managed Postgres (Fly MPG) provides a fully managed experience starting at $38/mo. For teams that want managed Postgres included in their platform cost rather than as an expensive add-on, Ancla includes it on paid plans.
Scaling growing pains
Fly.io's leadership has been publicly transparent about scaling challenges the platform has faced. GPU support was offered and subsequently deprecated after proving difficult to sustain. Community forums document periods of reliability concerns. To their credit, Fly.io has addressed these openly and continues to invest in platform stability. But for teams evaluating production infrastructure, the track record is part of the decision.
